Hi Hongbin, Regarding HBase patch policy: It's a case by case decision. We welcome you to ask for what you need, or propose changes/patches you'd like to see committed. Committers will look at if APIs are added or changed, what areas of functionality are impacted, if we can meet our compatibility promises, and make judgements about stability and maintainability risks.
In this case we are looking at a filter, which is a small self-contained component. Because it is an isolated change it is low risk in my opinion. If we did commit this to 0.98 it would be also committed to the other active branches too. The next releases made from any of those branches would have the feature. However, unless you are ok with telling your users that certain minimum versions of HBase are required, you should not depend on new HBase features. Maybe this isn't important enough for that? Anyway, just let me say if you do have requests or questions for HBase developers, please feel free to open an HBase JIRA or mail us at [email protected]. > On May 4, 2015, at 6:33 PM, hongbin ma <[email protected]> wrote: > > hi, andrew > > i'm always curious about hbase's(or any apache project's) patch policy. > I mean, how does a committer decides which branches to rebase the patch? > Is 0.98 or 0.94 still receiving new feature patches? > > And what would your suggest considering Luke Han's concern in last email? > >> On Sun, May 3, 2015 at 11:23 PM, Luke Han <[email protected]> wrote: >> One concern I have is: if we go and depends on this feature, that mean any >> installation has to patch this feature in there own cluster.
